didStartUserGesture method
override
The Navigator's routes are being moved by a user gesture.
For example, this is called when an iOS back gesture starts, and is used to disable hero animations during such interactions.
Implementation
@override
void didStartUserGesture(Route<dynamic> route, Route<dynamic>? previousRoute) {
assert(navigator != null);
_maybeStartHeroTransition(route, previousRoute, HeroFlightDirection.pop, true);
}
